I am slightly confuzzled with what's going on here. I only bought these a few days back and it's only really been the first time I've used them but whenever they dry they take this shape:
It also does this after the first stroke of paint onto a model.
Really confusing me.
Can't tell if this is normal or not , doesn't seem it as it ruins the painting after 1 stroke and forces me to wash the brush again to get it to conform into it's usual shape without it painting lines over everything.
Could be as Foster has said, you can give them a clean in boiling water to completely clean them. How are you storing them? It looks like you've put them bristle-down in a pot or something and they've frayed.
It looks like a very, very light beige colour with a pure White highlight. I haven't familiarised myself with the new GW paint names as I use Vallejo so I can't give you specific colours, but it may be something like a mixture of Kommando Khaki + White, with either a light Grey wash or a pale Brown, and then a final strong highlight of White.
